This invention relates to new and useful improvements in a bread rollfilling machine.

The invention has for an object to provide ina machine of the classmentioned a 'carriage supporting roll Acutting tools, and-heatingwindings individually within each of the tools. Y

Another object of this invention is to provide a roll holder beneatheach of the above mentioned tools which is selectively pivotal laterallyfor receiving filling and then vertically, and means for simultaneouslypivoting said roll holders.A

A still further object of this invention. is the provision of a heatinggrid with a plurality of discharging compartments' individually heated.

A still further object of this invention is the arrangement ofthecompartments and gangs and each gang to include one mastercompartment, means for individually discharging the contents of all thecompartments eXcept the master, and for simultaneously discharging allof the compartments upon discharge of the master.

A still further object of this invention is the provision of a device ofthe class men'- tioned which is of simple durable construction,dependable in use and eiiicient in action, and which can be manufacturedand sold at a reasonable cost.

For further comprehension *ofthe invention, and of the objects andadvantages thereof, reference will be had to the following dedrawing,'and to the appended claims in W ich the various novel features of theinvention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosureFig. 1 is a perspective view of a device constructed according to thisinvention.

The bread roll filling machine comprises a frame 10, a plurality of rollholders 11 pivotally mounted on said frame for assuming verticalpositions and movable to the horizontal, a carriage 12 movably mountedon 55 the frame 10 and supporting roll halving tools 13 for engaginginto rolls in the said rollers 11 when the latter elements are inthevertical, a gang of compartments14 on said frame 10 associated withpistons 15 to dis- 60 charge food from the compartments into rolls insaid roll 4holders 11 in the horizontal positions of the latterelements, one of said compartments being a master and indicated byreference numeral 14', and means for dis- 65 charging the contents ofall compartments simultaneously with discharging of the master and fordischarging'each compartment selectively except said master.

Each of the roll holders 11 comprises a 70 tubular member which isclosed at the bottom 16 and opened at the top 17. A longitudinal slot 18extends from the top down substantially half way so that an implementmay be inscerted to pry a roll out from the 75 holder. In Fig. 2 a` roll19 has been shown within the holder, and within the roll there is aFrankfurter 20. The frame 10 is provided with a base plate 21 'uponwhich the roll holders 11 are mounted. The mounting 80 consists in atransverse rod 22 extending com pletely across the device and out frombot-h sides and terminating at the ends in handles 23. Hinges 24 areconnected between the base plate 21 and each ofthe holders 11 and 85 arearranged upon the rod 22. Fingers 25 project from the rod 22 beneatheach of the holders 11 so that when the handle 23 is rotated though anangle of substantially 90, these fingers cause all ofthe roll holders to90 lmove to the. horizontal. The horizontal position is indicated inFig. 1, and also by dot and dash lines 26. The frame 10 is provided withside bars 27 supporting/a transverse bar 28 which serves as a rest tolimit the downward pivoting of the roll holders to the horizontal.

T-he carriage 12 is in the form of an angle iron having a horizontalframe 29 and a vertical'arm 30. Themovable mounting of the 100 carriageis accomplished by Vcables 31 attached upon the horizontal arm 29 atboth of its ends and extended over idler pulleys 32 rotatively supportedupon the frame 10, Counterweights 33 are attached upon the other ends ofthe cables 32 so as to counter` balance the carriage. Covers 34 areattached upon theside of the frame 10 and cover the counterweights 33.The frame 10 also includes a cross bar 35 arranged across the front ofthe carriage 12 at the top of the frame. A pin 36 pivotally engagesthrough the bar 35 and at one end rigidly connects with a handle 37,while at the other end rigidly connects witha lever 38. Another pin 39projects from the free end of the lever 38 and works in a slot 40 formedin the horizontal arm 29 of the carriage 12. When the handle 37 is moveddownwards, the lever 38 will move correspondingly and cause the carriage12 to be forced down.

The roll cutting tools 13 are arranged directly'over the roll holders11- and are-correspondingly spaced and of the same number so that thereis one cover for each of the holders. Each of these cutting tools.includes a heating element. The construction comprises a shell 41threadedly engaged within the horizontal arm 29 of the carriage andholding a pointed hollow member 42. A stem 43A is supported within theshell 41 and has a reduced portion presenting a space between theinterior of the pointer member 42. A heating winding 43v is arrangedIupon the stem and within thisA space. Each of the heating tools may beremoved and repaired whenever necessary.

A plate 45 is attached across the side bars 27 and supports a slidablebase plate 46. The

. dial ar'ms 52 are rigidly attached upon the rod 50 and carry pinsl 53capable of acting against lugs 54 projecting from the slidable plate 46.When the pins engage against these lugs, they restrain the springs 49from moving the plate towards the holders 11.v When the handles 51 areraised, the springs 49 are free to move the plate.

Each of the compartments 14 is in the form of a cylinder having bothends open. This is very clearly shown inl Fig. 2. A cover 55 engagesover the cylinders 14 and closes their outer ends. The pistons 15 arearranged within the cover 54 so as t0 be capable of dischargingFrankfurters 56 or other food from within the compartments 14 when thepistons are moved forward. A griddlev 57 is mounted across the tops ofthe cylinders 14 so that a Frankfurter such as 58 or more may be restedthereon. Each of the cylinders 14 are provided with a heating unit 59 inthe form of a heating winding arranged around the cylinder. Heat fromthis' winding also reaches the grid 57 for keeping the Frankfurters 58or other food warm.

The cylinders 14 are arranged in gangs,

and as illustrated in Fig. 1 there are two gangs, four in each. Themaster cylinders 14 are'shown adjacent each other and the remainingmembers of the same gang are on opposite sides of these. The means fordischarging the contents of all of the compartments simultaneously withdischarging of the master and for discharging each compartmentselectively except said master comprises stems 60 attached uponthepistons 15 and rojecting from the cover 55. The stems o all of thecompartments except the master is formed with longitudinal slots 61, anda cross bar 62 is provided which is rigidly attached upon the stem ofthe master and carries pins 63 extending through the slots 61 of theother stems. The bar 62 is also shown connected across the second gangof compartments so that when either of the master stems are moved, allof the compartments will discharge.

The operation of the device may be traced by assuming it in thecondition as shown in Fig. 1. Frankfurters or other food should beengaged within the compartments 14, and rolls should be arranged withinthe roll holders 11. Then the handle 37 should be moved for causing thecarriage 12 to descend and the cutting tools 13 to enter and formincisions in the rolls. The cutting tool's should be allowed to remain ashort period of time within the rollsso as to toast the interior-s. Thenthe handle 37 should be moved to again raise the carriage.

Next handle 23 should be moved to move all of the holders 11 to thehorizontal. Then the handle 51 should be moved so as to release theplate 46 and allow the plate to slide forward to bring the compartments14 into close contact with the ends of the roll holders 11. Then thevarious stems 61 may be selectively depressed for dischargingindividually any of the compartments into the rollsor the stems of themaster compartments may be depressed for simultaneously discharging allof the compartments into all of the rolls. The plate 46 should then nextbe moved back into its position and thus held by the pins 53. Next theroll holders 11 should be moved to the vertical and the rolls with thecontents removed. In this manner they should be sold.

It is to be understood that the roll holders 11 may be of any suitableshape also they may be joined or-made of one single mem.- ber whichcontain a plurality of cavities for receiving the rolls.- l

It is also to be understood that the roll cutting tools may be soarranged that instead of moving same in a vertical direction, they maybe moved horizontally by a suitable mechanism.
